Method Detail
-
getName
public java.lang.String getName()
Description copied from interface:DataNode
Gets the name of this object. This is an intrinsic property of the object.- Specified by:
getName
in interfaceDataNode
- Overrides:
getName
in classDefaultDataNode
- Returns:
- the name of the object
-
getDescription
public java.lang.String getDescription()
Description copied from interface:DataNode
Gets a concise description of this object. The form of the description will depend on the type of node, but it might detail the shape or type of data represented, or otherwise give some information additional to the name. It should not include the return value of thegetName
method, since they may be presented together. It should be on one line, and preferably no longer than around 70 characters. Thenull
value may be returned if there is nothing to say.- Specified by:
getDescription
in interfaceDataNode
- Overrides:
getDescription
in classDefaultDataNode
- Returns:
- a short string describing this object
-
getNodeTLA
public java.lang.String getNodeTLA()
Description copied from class:DefaultDataNode
The DefaultDataNode implementation returns the string "...".- Specified by:
getNodeTLA
in interfaceDataNode
- Overrides:
getNodeTLA
in classDefaultDataNode
- Returns:
- "..."
-
getNodeType
public java.lang.String getNodeType()
Description copied from interface:DataNode
Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.- Specified by:
getNodeType
in interfaceDataNode
- Overrides:
getNodeType
in classDefaultDataNode
- Returns:
- a short description of the type of this
DataNode
-
hasDataObject
public boolean hasDataObject(DataType dtype)
Description copied from class:DefaultDataNode
The DefaultDataNode implementation returns true for only those data objects which have been registered usingDefaultDataNode.registerDataObject(uk.ac.starlink.datanode.nodes.DataType, java.lang.Object)
.- Specified by:
hasDataObject
in interfaceDataNode
- Overrides:
hasDataObject
in classDefaultDataNode
- Parameters:
dtype
- data object type of interest- Returns:
- true iff a subsequent call of getDataObject(type) is likely to be successful
-
getDataObject
public java.lang.Object getDataObject(DataType dtype) throws DataObjectException
Description copied from class:DefaultDataNode
The DefaultDataNode implementation returns any data object which has been registered usingDefaultDataNode.registerDataObject(uk.ac.starlink.datanode.nodes.DataType, java.lang.Object)

- Parameters:
dtype
- data object type of interest- Returns:
- data object of type type
- Throws:
DataObjectException
